usernames length

[Guest Tester]

Hello there,

What is the length of the login user names in AD? It seems to take no

more than 20 characters including the dot[firstname.lastname]. Any way

I can get around that limit? Thank you, T

I assume you mean the "pre-Windows 2000 logon name". The value for user (and

group) objects is limited to 20 characters. This is the NetBIOS name of the

object, so this is a limitation of NetBIOS. For computer objects the limit

is 15 characters. The sAMAccountName for computer objects is the NetBIOS

name plus a trailing "$", so the sAMAccountName of computer objects is

limited to 16 characters.
